Question

what is the rate of heat produced at 1000W ? what is the heat produced in 1 hr​

Answer 1

Answer:

The Heat produced is 8.5*10⁶ cal.

Explanation:

Given,

Electric Power = 1000W

Time = 1hr

Units = [Wattage*Time]/100

= [1000*1]/100 kWh

= 10 kWh

Now,

= 1 kWh = 3.6*10⁶J

= 10 kWh = 3.6*10⁶⁺¹ J

= 3.6*10⁷ J

4.2 J is equal to 1 calorie.

So,

= [3.6/4.2]*10⁷ cal

= 0.85*10⁷ cal

Or,

= 8.5*10⁶ cal

Hope this helps.

Answer 2

Answer:

The Heat produced is 8.5*10⁶ cal.

Explanation:

Given,

Electric Power = 1000W

Time = 1hr

Units = [Wattage*Time]/100

= [1000*1]/100 kWh

= 10 kWh

Now,

= 1 kWh = 3.6*10⁶J

= 10 kWh = 3.6*10⁶⁺¹ J

= 3.6*10⁷ J

4.2 J is equal to 1 calorie.

So,

= 0.85*10⁷ cal

Or,

= 8.5*10⁶ cal
